M-QAM modulation has been considered to achieve high bandwidth efficiency for wireless communications. However, due to its envelope fluctuation, it exhibits large spectral regrowth and performance degradation when the transmit power amplifier (PA) operates in a non-linear region close to saturation. In this thesis, two different Adaptive Predistorters (PD) are evaluated and a new algorithm is introduced which shows faster convergence when there is no prior information about the PA… CONTINUE READING
